EBPECIPICATION forming part of Letters Patent N0. 361,840, dated April 26, 1887.

provide a simple, inexpensive, and effeetive device 0f this charaeter which is adapted for use with either right: er left hand doors 01 gates, and will operate easily, quietly, and automatically as the door 01 gate is opened to hold itzopen, and may be readily disengaged 130 allow t-he door to be closed.

The invention consists in certain novel feabares of construetion and oombinations 0f parts of the door-cheek, all as hereinafter fully described and elaimed.

Reference is so be had to the aceompanying drawings,forming a parb.of this speoification, in which similar letters of reference indicabe conesponding parts in all the figures.

Figure l is a perspective view ofthe inberior 0f a room, showing our improved door-cheek in operative position. Fig. 2 is a front elevation 0f tlie main parts of our door-check. Fig. 3 is a plan view thereof, Fig. 4 is an end view of the parts shown in Fig. 2, wibh the eatch-plate,which is shown in vertieal section. Fig. 5 is a front view of the catch-plate; and Fig. 6 is a plan view of the catch-plate, with the end of the latch indicated in dotted lines.

The door-cheek eomprises a latch device, A, to be atta'ohed to the base-board or wall, and a eateh, B, whieh is 130 be attaehedto the face of a door, as shown in Fig. 1 of the drawings,

. and whereby as the door is opened its catch will be automatically engaged by bhe latch, as hereinafter more fully explained.

The lateh device is made preferably with a base-plate, O, having a lag, 0, 110 whioh the lateh-bar D is pivoed ab its inner end by a pin, E. The outer end of the latch-bar is formed as a hook, d, which is adapted to engage a recess, b, in t-he upper face of the catoh B, as

shown in Fig. 4 of the drawings, and bhe piv oted end 0f the latch-bar is formed wibh a shoulder, e,which by striking the base-plate O, prevents fall of the bar below a horizontal positiom Y A lever, F,whieh is pivoted atf, about ab its center, to Ehe base-platze C,is benb outward als 0ne end, and t hen ce parallel withthebaseplate, to form a pin, f,which enters a hole, d,made in the latch-bar D, and the opposite end of bhe lever is also bent 01 shaped With a projection, f whieh 1's preferably serrated 01 roughened ab both upper and lower faces,to prevenb easy sl1'p of the footfrom lt in operating the door- Check to release the door, as presently described. Lugs G H, casta on the base-plate, form stops to limils bhe depression of the lever, and eonsequenbly the rise 0f tahelateh-bar, wheu disengaging Ehe bar from the catch-plalze.

As shown most clearly in Figs. 5 and 6 of the drawings, bhe catch-plate -B has a semicircular form ab its front: part, and its recess b has a like form at its outer edge er Wall, and the outside face 0f the semicircular front of the platze is beveled 01 rounded over, as ab b, 110 allow the beveled, or inelined face (Z 0f the latch-bar hook d to readily engage With the cateh-plate by riding overibs face b and dropping into the recess b.

'lhe operabion 0f the device is very simple and effeet;ive, and as follows: \Vhen the door I, to which the eatehplateB is fixed, :ls opened, lzhe eatch-plate Will lifb the lateh-bar so its hook d will automatioally engage ehe catch-plate by dropping into its recess b, as in Fig. 4, and the door Will be hold open. T0 close the door, a person will press 0n the end f 2 of the latch-lever with the foot, whieh Will lifiz the hook d from the recess b and allow the door 120 be swung shut. Thehorizontally-rounded front;

of the catoh-plate and its Correspondinglyshaped recess allow the engagement; of uhe latch-bar With the catch-plate 11017 only when Ehe base-looard 0r wall 130 which the latch A is fixed is in the same plane witah the closed door, bat; also when the labch is fixed 130 a Wall standing ab right angles to the closed door or ab any intermediate angular position, and as will be understood from the dotbed position o1" the lateh-bar in Fig. 6 of the drawings.

It is obvious bhab by removing the pivot E 0f bhe latch-ba'r and turning the bar upside down,and turning the base-plate, o0 which the latch-bar is again pivoted, the otaher edge up when attaching it 110 the base-board or Wall, the latch may be used to catoh and hold doors opening either to the right er left band, the

ing them out of shape, as the engagement of the 1atch with the catehis very easily effeeted, and, witha], wibhout jar 0x noise. Furbherrymore, the door-cheek is elear of the E1001 and does not interfere with carpets or other 13001;- covering, and there are no springs er other fragile parts to the cheek which are liable t0 be easily broken 0r t0 geb 0ut oforder, andfinally, the entire device is very e asily made .and ab a -trifling c0st-, and may be applied and operated by any person of ordinary intelligence.

Although the drawings represent the preferred forn1 of device, Lhe base-plate O maly be dispensed with witahout departing from the spirib of our invention, and in this caSe the lateh-bar D and 1ever F would be pivoted directly t0 the base-board or wa1l 01' fenee, as the Gase may be, und. in relatively operative positi 0ns above described.

Havinigthus d escribed our' inventi0n, what we c1a'im as new, and desire to secure by Letters Patent, is

1. In a door-check, the combinabion, wibh the base-plate C, provided with the Ing c and V the stops G H and a catch-plate- 0f the hook D, pivo'laed eo the 1ug 0 und provided with the hole d, and the lever F, pivoted 130 the plate 0 and provided Wibh the pin f, entering t-he aperlaure d in the hook, substantially as herein shown and deseribed.

2. In a door-check, the combination, With the semicirculan catch-plalbe B, having a correspondingly-shaped recess, b, in its upper face, 0f the plate O, the 1100k D, pivoted 130 the plate 0 and provided With the aperture d, and the 1ever F, pivoted t0 the saidplate O and provided with the pin f,fitting in the aperture of ehe hook, substantially a.s herein shown and desdribed.

3. The catch-plate B, of semicircu'lar form and having a correspondingly-shaped recess, b, in its upper face, and bevelededges b, substantially as herein shown and-described.
